Experimental study demonstrates broadband subwavelength imaging using an all-dielectric magnifying lens, suggesting viable far-field high-resolution microwave applications.
A transformation-optics magnifying lens is reported in the microwave frequency, which is made of inhomogeneous but isotropic dielectrics to reach impedance matching. The authors demonstrate the broadband subwavelength imaging performance and magnification factor experimentally from the far-field radiation patterns.
